The cloud has dramatically changed how business applications are built and run. Delivering a new application is now as fast as opening your Internet browser. Platform as a service (PaaS) is a proven model for running applications without the hassle of maintaining on-premises hardware and software infrastructure at your company.

Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications. You purchase the resources you need from a cloud service provider on a pay-as-you-go basis and access them over a secure Internet connection.

Like IaaS, PaaS includes infrastructure—servers, storage, and networking—but also middleware, development tools, business intelligence (BI) services, database management systems, and more. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing, and updating.

Common PaaS scenarios

Organizations typically use PaaS for these scenarios:

• Development framework
• Analytics or business intelligence
• Additional services

Advantages of PaaS

By delivering infrastructure as a service, PaaS offers the same advantages as IaaS. But its additional features—middleware, development tools, and other business tools—give you more advantages:

• Cut coding time
• Add development capabilities without adding staff
• Develop for multiple platforms—including mobile—more easily
• Use sophisticated tools affordably
• Support geographically distributed development teams
• Efficiently manage the application lifecycle

DaaS stands for Desktop-as-a-Service. When you have a DaaS solution, you work on a virtual desktop infrastructure hosted in the cloud. Because the cloud-based desktop is stored on a remote server, it is separate from the physical devices which access it. With hosted desktop services, a third-party provider handles data storage, security, backup, and upgrades while your employees focus on driving your business forward.

Desktop as a Service (DaaS) frees your business from the endless cycle of purchasing, supporting, and upgrading PCs by delivering access to an untethered “virtual” workspace.

DaaS is available to several types of computer devices, including handheld units, laptops and desktop units. DaaS is an economical substitute to conventional IT solutions and is used by companies and organizations that need an optimum level of mobility and performance.

Why DaaS?

There are several reasons to select DaaS. Here are just some of the benefits DaaS offers your organization.

• Mobility and Productivity
• Predictable Costs
• Business continuity
• Free up IT resources

Advantages of DaaS :
 

• Data Security
• Reliability
• Personalization
• Increase in Performance
• Uninterrupted Connectivity
• Disaster Recovery
• Minimized Complexity
• Total Cost Resuction
• Easy Platform Migration

A virtual private cloud (VPC) is a private cloud located inside a public cloud that enables you to experience the benefits of a virtualized network while using public cloud resources.
A VPC is ideal for companies seeking high levels of security, privacy and control, such as healthcare and financial organizations dealing with regulatory compliance. Businesses also find VPC ideal for running mission-critical applications.
You usually manage a VPC through a managed service provider’s control panel. This window into your VPC enables you to easily see and make changes as needed.

Why Use a Virtual Private Cloud?

Enhanced Security:
A VPC allows you to secure your virtual networking environment, including your IP addresses, subnets and network gateways. For instance, you can securely isolate a database in a private-facing subnet that isn’t connected to the internet.
Data Control:
Your VPC is isolated from other clouds at the network layer, so you control your data and prevent it from mixing with the data of other entities — a potential risk of public clouds
Improved Performance:
You can prioritize the network traffic of select applications to optimize their performance, helping to eliminate congestion and potential bottlenecks.
On-Demand Flexibility:
You can design the cloud architecture that best serves your company’s needs. For example, you can set up your VPC for contractors to use individual direct connections that aren’t routed through your internal network.
 

Cloud storage is a cloud computing model that stores data on the Internet through a cloud computing provider who manages and operates data storage as a service. It’s delivered on demand with just-in-time capacity and costs, and eliminates buying and managing your own data storage infrastructure.

Cloud storage is a service that lets you store data by transferring it over the Internet or another network to an offsite storage system maintained by a third party.

Storage systems are typically scalable to suit an individual’s or organization’s data storage needs, accessible from any location, and are application-agnostic for accessibility from any device. 

Cloud Storage Main Models:

• public cloud storage service that suitable for unstructured data,
• private cloud storage service that can be protected behind a company firewall for more control over data
• hybrid cloud storage service that blends public and private cloud services together for increased flexibility.

Benefits of Cloud Storage

• Total Cost of Ownership
• Time to Deployment
• Information Management
